Hrmmm... I do have two Rivulus tenuis males sitting around and taking up space in my Ancistrus tank. Maybe I'll add a couple inches of water to give them easier access to the bugs and toss them in... might as well put them to good use since they're not making babies anytime soon. Thanks for the tip.
Niko, I have enough issues with those little gnat things that occasionally fly into peoples' mouths (or eyes); I'm not about to start tasting bugs on purpose. :P
Michael, you can keep your ants. I'm trying to kill the aphids, not hire babysitters for them.

FWIW, you might try getting one of those big gallon ziplock bags - especially the kind with the little zipper tabs built in - and sealing the bag(s) of sugar in there. Works for us to keep the stupid pantry moths out of our food
